[0005] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a blockage clearing knife is provided, including a blockage clearing knife, wherein the blockage clearing knife includes an installation section and a cleaning section integrally formed with both ends of the installation section, wherein the outer diameter of the installation section gradually decreases from the center to both ends, and the outer diameter of the cleaning section gradually increases from one end toward the installation section.

[0006] Furthermore, the blockage clearing knife has a flat conical structure.

[0007] Furthermore, the two side walls at the center of the installation section are convex structures.

[0008] Furthermore, the blockage clearing knife is inclined 0-5° from both ends to the center in a bow shape.

[0009] On the other hand, the present invention provides a tool holder structure for a blockage clearing tool, which is used for a blockage clearing tool as described in any one of the above, including a tool holder, a mounting groove being provided through the tool holder, one end of the blockage clearing tool being inserted into and mounted in the mounting groove, and the inner diameter of the mounting groove gradually decreases from top to bottom.

[0010] Furthermore, the aperture of the mounting slot is adapted to the shape of the blockage clearing knife.

[0011] Furthermore, the inner diameter of the installation slot at the smallest aperture is smaller than the outer diameter of the central protrusion of the installation section.

[0012] Furthermore, the blockage clearing knife is inserted from above the mounting groove until the central protrusion of the mounting section is snapped into the mounting groove, so as to fix the blockage clearing knife.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The plug-in design is adopted in the blockage clearing knife and its knife seat structure, and no additional tools such as screwdrivers or wrenches are needed, which simplifies the installation and disassembly process of the blockage clearing knife, improves work efficiency and reduces maintenance costs.

[0015] 2. In this kind of blockage clearing knife and its knife seat structure, the blockage clearing knife adopts a structural design in which the outer diameter of the mounting section gradually decreases from the center to both ends, and the outer diameter of the cleaning section gradually increases from one end toward the mounting section, and is used in conjunction with the mounting groove. As the tool goes deeper, relying on its own structure, gravity and the centrifugal force generated during work, the blockage clearing knife can automatically clamp in the mounting groove without the need for bolt fixation, thereby ensuring stability during work and reducing the risk of loosening due to vibration or external force impact.

[0027] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0028] Example 1

[0029] See also Figure 4-Figure 7 As shown, the purpose of this embodiment is to provide a blockage cleaning knife, including a blockage cleaning knife 3, the blockage cleaning knife 3 includes a mounting section 31 and a cleaning section 32 integrally formed with both ends of the mounting section 31, wherein the outer diameter of the mounting section 31 gradually decreases from the center to both ends, and the outer diameter of the cleaning section 32 gradually increases from one end toward the mounting section 31.

[0030] The cleaning knife 3 is a flat conical structure, and the flat surface of the cleaning knife 3 is in contact with the inner wall of the blanking pipe, and is used to clean the inner wall of the blanking pipe; at the same time, since the inner wall of the blanking pipe to be cleaned is an inclined design that gradually decreases from top to bottom, Figure 7 As shown, the cleaning knife 3 is inclined at 0-5° from both ends to the center in a bow shape, so as to ensure that the flat surface of the cleaning knife 3 always fits the inner wall of the blanking tube, and as the cleaning section 32 is longer, its inclination angle is larger.

[0031] In order to meet the installation requirements of the clearing knife 3 , the two side walls at the center of the installation section 31 are convex structures, and the installation section 31 can be snapped into the installation groove 21 to fix the clearing knife 3 .

[0032] Example 2

[0033] See also Figure 1-Figure 3 As shown, the purpose of this embodiment is to provide a tool holder structure of a cleaning knife for installing a cleaning knife 3, the tool holder structure of the cleaning knife includes a tool holder 2, and a mounting groove 21 is opened through the tool holder 2, wherein the aperture of the mounting groove 21 is adapted to the shape of the cleaning knife 3, and since the surface of the cleaning knife 3 is designed to be flat, in order to meet the fixation of the cleaning knife 3, when the cleaning knife 3 is in a stable fixed state, the inner wall of the aperture of the mounting groove 21 needs to be tightly fitted with the outer wall of the cleaning knife 3, and the inner diameter of the smallest aperture of the mounting groove 21 is smaller than the outer diameter of the central protrusion of the mounting section 31. Therefore, when the cleaning knife 3 is inserted from the top of the mounting groove 21 until the central protrusion of the mounting section 31 is stuck in the mounting groove 21, the cleaning knife 3 is fixed;

[0034] In summary, the blockage clearing tool 1 is composed of a blockage clearing tool 3 and a tool holder 2, and they are used in combination. One end of the blockage clearing tool 3 is inserted into and installed in the mounting groove 21, and the inner diameter of the mounting groove 21 gradually decreases from top to bottom. Due to the structure of the blockage clearing tool 3 with narrow ends and wide center, when the blockage clearing tool 3 is inserted into the mounting groove 21, as the blockage clearing tool 3 goes deeper, until the mounting section 31 of the blockage clearing tool 3 is inserted into the mounting groove 21, the blockage clearing tool 3 has an outer diameter size of its mounting section 31 larger than the inner diameter size of the smallest aperture of the mounting groove 21, so that the blockage clearing tool 3 is clamped and installed in the mounting groove 21. With the combined effect of gravity and centrifugal force when the blockage clearing tool 3 is working, the blockage clearing tool 3 is clamped and installed tighter and tighter, thereby realizing a boltless blockage clearing tool 3 installation method, and the blockage clearing tool 3 can be installed and removed by plugging and pulling. The interference fit design of the mounting section 31 and the mounting groove 21 increases the stability of the tool during work, especially when rotating at high speed or bearing a large workload, it can maintain a good dynamic balance, thereby extending the service life of the tool.
